Injection Moulding Machine for Medical Device Housings
Medical device housings are made on horizontal injection moulding machines from PC, PC/ABS or ABS, with front and rear halves in separate or family moulds. Machine size is set by the projected area of the larger half, shot weight against barrel capacity and mould height for deep walls. Low moulded-in stress matters most, because disinfectant wipes crack stressed polycarbonate.
For housings, selection looks at steady holding pressure, mould temperature control and a clamp that suits the largest half. Pratishna Engineers supplies horizontal injection moulding machines for device enclosures and can recommend a set-up, with any clean moulding area specified by the device maker.

Machine Requirements for Medical Device Housing Moulding
Device housings are cosmetic enclosures that must also survive years of cleaning. Selection usually turns on these points:
- Dried PC and PC/ABS to avoid splay on visible faces
- Low moulded-in stress against cracking from disinfectant wipes
- Packed screw bosses without sink on the outer face
- Weld lines kept away from display windows and button holes
- Mould height and opening stroke for deep housing walls
- Steady mould temperature for even texture and gloss
Recommended Machine for Medical Device Housings
Handheld monitor and meter housings are small to medium mouldings and often run on the E Series (75-180 T). Bench instrument covers, larger front panels and family moulds carrying both halves need more clamp and platen space, which points to the C Series (140-320 T) or H Series (120-350 T).

FAQs / Buyer Questions
Questions device makers and their moulders raise when they plan housing production.
Which Injection Moulding Machine Is Used to Make Medical Device Housings?
A horizontal machine sized to the larger housing half. Small handheld covers usually sit in the E Series, while instrument enclosures and two-half family tools move up to the C or H Series depending on mould size.Why Do PC Housings Crack After Cleaning?
Polycarbonate holds stress from high holding pressure, a cold mould or tight snap-fits. Alcohol and disinfectant wipes then open fine cracks around bosses and clips. Lower packing, a warmer mould and generous radii reduce it, and PC/ABS blends can resist chemicals better.Does PC Need Drying Before Moulding?
Yes. PC and PC/ABS absorb moisture, which shows as silver streaks and lowers impact strength. Resin goes through a dryer before the hopper, and residence time in the barrel is kept short to avoid yellowing on light grey or white housings.
Can Metal Inserts Be Moulded Into Device Housings?
Threaded brass inserts can be loaded into the mould before injection or pressed in after moulding with heat or ultrasonics. Moulded-in inserts add a loading step and slow the cycle, so many moulders fit them after ejection.Can Pratishna Recommend a Machine for My Medical Device Housing?
Yes. Share the housing drawings or samples, resin grade, weight of each half, mould dimensions, whether both halves share one mould and the yearly quantity, and Pratishna Engineers will suggest a suitable machine.Does the Machine Suit Other Medical Equipment Parts Too?
Yes. A machine in this class can also mould test kit housings, internal mechanism parts and levers, diagnostic test cassettes and medication trays, subject to the mould and material.
